Controlling access to content on an object addressable storage system
First Claim
1. A method of accessing a content unit stored on an object addressable storage (OAS) system, the content unit having a first portion and a second portion and being identified via an object identifier that is, from the perspective of a user accessing the content unit on the OAS system, independent of a storage location of the content unit on the OAS system, the method comprising acts, performed by at least one hardware processor, of:
- assigning a first set of access permissions to the first portion of the content unit, wherein the first set of access permissions specifies a first set of users permitted to access the first portion of the content unit, wherein the act of assigning a first set of access permission to the first portion of the content unit further comprises acts of;
storing metadata on the OAS system that defines the first portion of the content unit; and
storing metadata on the OAS system that defines the first set of access permissions for the first portion of the content unit; and
assigning a second set of access permissions to the second portion of the content unit, wherein the second set of access permissions is different from the first set of access permissions, and wherein the second set of access permissions specifies a second set of users permitted to access the second portion of the content unit,wherein the OAS system is a content addressable storage (CAS) system, and wherein the object identifier that identifies the content unit is a content address that is generated, at least in part, from at least a portion of the content of the content unit.

Abstract
Embodiments of the invention relate to controlling access to a content unit stored on an object addressable storage (OAS) system. In one embodiment, the content unit may have an object identifier that is used to identify it on the OAS system. A first portion of a content unit may be assigned a first set of access permissions and a second portion of the content unit may be assigned a second set of access permissions that is different from the first set of access permissions.

5. At least one non-transitory computer readable medium, encoded with instructions that, when executed, perform a method of accessing a content unit stored on an object addressable storage (OAS) system, the content unit having a first portion and a second portion and being identified via an object identifier that is, from the perspective of a user accessing the content unit on the OAS system, independent of a storage location of the content unit on the OAS system, the method comprising acts of:
-
assigning a first set of access permissions to the first portion of the content unit, wherein the first set of access permissions specifies a first set of users permitted to access the first portion of the content unit, wherein the act of assigning a first set of access permission to the first portion of the content unit further comprises acts of; storing metadata on the OAS system that defines the first portion of the content unit; and storing metadata on the OAS system that defines the first set of access permissions for the first portion of the content unit; and assigning a second set of access permissions to the second portion of the content unit, wherein the second set of access permissions is different from the first set of access permissions, and wherein the second set of access permissions specifies a second set of users permitted to access the second portion of the content unit, wherein the OAS system is a content addressable storage (CAS) system, and wherein the object identifier that identifies the content unit is a content address that is generated, at least in part, from at least a portion of the content of the content unit. - View Dependent Claims (6, 7, 8)

9. An object addressable storage (OAS) system that stores a content unit having a first portion and a second portion and being identified via an object identifier that is, from the perspective of a user accessing the content unit on the OAS system, independent of a storage location of the content unit on the OAS system, the OAS system comprising:
-
an interface that receives an indication of a first set of access permissions for the first portions of the content unit and a second set of access permissions, different from the first set of access permissions, for the second content unit, wherein the first set of access permissions specifies a first set of users permitted to access the first portion of the content unit and wherein the second set of access permissions specifies a second set of users permitted to access the second portion of the content unit; and at least one controller, comprising at least one processor and coupled to the interface, that; assigns the first set of access permissions to the first portion of the content unit; assigns a second set of access permissions to the second portion of the content unit; stores metadata that defines the first portion of the content unit; and stores metadata that defines the first set of access permissions for the first portion of the content unit, wherein the OAS system is a content addressable storage (CAS) system, and wherein the object identifier that identifies the content unit is a content address that is generated, at least in part, from at least a portion of the content of the content unit. - View Dependent Claims (10, 11)
